How long to leave an oyster in the tank?

[daniella3d]

That copperband is getting fat now. So far I have put a large oyster 3 days ago, yesterday I put a mussel, today I put another oyster. He's picking at it bit by bit all day long, plus he gets live white worms. I tested ammonia today and it was zero. Tested nitrates and was zero.

What would be the sign of my system overload with waste? I guess first sign would be nitrates?
